likely extremely difficult to find since it's super-niche technical engineering info. Like, why would that even be online for the public to access if there's better and more important priorities for NASA to fund with it's strict budget, but we'll look tomorrow.

You're worried about that and Chandra might get shut down due to lack of funding...

The LM was unoccupied during TLI coast, so it sounds like you want information on the command module with regards to the VAB and then...something about the LM.

Please be more specific.

Apollo missions took around 30 minutes to traverse the interior, proton heavy Van Allen belts. During that time astronauts were inside the CSM which had some radiation shielding, but still dosimeters registered less radiation in 10 day Apollo missions than what astronauts recieved in longer duration Skylab or ISS missions in low earth orbit.

Correct, they "solved" it by putting it in orbit a few hundred km below the Radiation belts. Coincidentally at a similar height to the ISS

It deflects radiation towards the earth’s poles. Which makes me wonder, wouldn’t polar expeditions get a heavy dose of radiation?

thankfully the trajectory used to get to the moon avoided everything but the weakest areas of the the belts.

>the CSM which had some radiation shielding
when you take into consideration the materials used on the CM (stainless steel, fibrous insulation, honeycomb aluminum) and all of the equipment attached to the inside, there was really quite substantial shielding. I've read that the average density came to around 7 or 8g/cm2.

And of course, the entire mass of the SM was always right behind them, adding a huge amount of protection in that direction.

The marvel is called "not giving a fuck about the human guinea pigs on board".
Most of them were test pilots for a reason.
Nonetheless radiation was measured by previous non-manned probes and deemed safe for the trajectory.

yes, but what you'll never see is the ones asking the question doing any research into the actual radiation environment in the VAB. This is because its a question they get from retarded shit like American Moon, which gives no real information at all but just enough waffle to encourage lazy thinkers to call Apollo fake.

I know that anon, I know that well, but it's a legitimate question and they have aright to ask it, especially on the science board.

Not true. These men were extremely valuable people to the space program with countless hours as test pilots, engineering degrees and extensive careers in the military and training. The loss of each of them was not only a personal loss but also from an economic standpoint.

You can 'pass through' higher radiation than you seem to fail to understand. Exposure time is what matters.

Your pic is misleading. Real life is 3D, obviously. The radiation belt is like a belt; it's ring-shaped. Apollo spacecraft mostly went OVER it, just skirting it very briefly.

how is it misleading? it shows altitude above sea level over time. and yes of course real things exist in three dimensions. its a cross sectional view.

i think each of those red dots indicates the passage of 10 minutes by the way. you can see how they began to slow as altitude increased. The only thing that is properly represented could be that the VAB are not aligned with the geographical equator, instead being offset by about 20 degrees or something.

A proper cross-sectional view wouldn't show the trajectory of the spacecraft at all because it's not in the cross-sectional plane. It's UP. (Or down, I can't remember if they went north or south.) That's how they avoided the belt.

Picrel shows the groundtrack for the apollo 11 stack from TLI to a couple hours later. you can see how they quickly get up above the inner VAB (yellow band) and then begin to slow as they travel up the gravity well.

The average background radiation at the poles does end up being *slightly* higher, but it's like a few percent higher, not orders of magnitude. A lot of this is due to the magnetic mirror effect - the reason the belts exist in the first place is because as you go down to a region with a higher magnetic field gradient (closer to the poles), the field redirects kinetic energy from motion parallel to the field to perpendicular to the field, until eventually the particles stop and get reflected back out towards the equator. Aurora are the result of especially energetic particles in CMEs and shit that have enough energy to make it to higher latitudes and lower altitudes and can interact with neutral gasses in the upper atmosphere instead of getting reflected.

Exposure time and shielding. The biggest misconception is how little shielding is actually required to cut out most of the alpha and beta radiation that are the real dangers in the belt. Alpha particles can be blocked with a sheet of paper or the layer of dead skin on the outside of your epidermis, beta radiation can be blocked by a few millimeters of aluminum.

Most of the chronic radiation exposure that station crews deal with is gamma radiation, cosmic rays, shit that you can't really shield against without huge panels of lead or hundreds of kilometers of atmosphere. You don't get a massive dose of that shit in a few days, but if you're doing six months on the ISS that cumulative exposure adds up.
